TPS65235 LNB Voltage Regulator with I2C Interface Evaluation Module for DisEqC2.x


Order now


The TPS65235EVM-694 evaluation module (EVM) is a fully assembled and tested circuit for evaluating the TPS65235 for DisEqC2.x application. The EVM contains input and output connectors as well as control jumpers to easily evaluate the device features. Compared with TPS65235EVM-747, the TPS65235EVM-694 has circuits for DisEqC 2.x support. The TPS65235 is a monolithic voltage regulator with I2C interface, specifically to provide the 13 V / 18 V power supply and the 22 kHz tone signaling to the LNB down-converter in the antenna dish or to the multi-switch box.

  • Supports  5 V, 12 V and 15 V  power bus
  • Up to 1000 mA accurate output current limit adjustable by external resistor
  • Boost switch peak current limit proportional to LDO current limit
  • Dedicated Enable Pin for Non-I2C Application
  • Boost switching frequency 1MHz/500KHz selectable
Boost converters (integrated switch)
